Can anyone tell me why the crack in the cab paint above the rear of the door. Is it from flexing of the frame in that area? I've seen it in several of the pickups besides mine. Thanks Mike

Sounds good enough for reasoning. Mine is cracked there too.

I wonder if it is a joint where the top is welded to the rear quarter? Maybe you can look under the head liner. G.M.

Looks like G.M. is right. Top to quarter panel joint, welded/brazed & leaded, from what I've seen.

As I understand. Ford filled that seam on '40 and '41s. Not on '42 and up. Yes they do crack. Mine is also.

Seth Swoboda · 03-09-2012, 09:52 AM

They are all correct. That is a body joint that was leaded/welded together at the factory. My 39 was cracked here also before it was repainted.

Shadetree · 03-09-2012, 03:42 PM

Now this is a leaded joint!

Pete Fl/Wi · 03-09-2012, 04:23 PM

My 39 has same issue.

Could it be that the 1/2 Ton cab mounting setup is too rigid? Attached are photos of the cab mounting blocks on my 1940 Tonner. There are a total of 6 blocks - 3 on each side and the cab is secured to the frame with spring isolated bolts so that the cab can move independent of the frame. There were no cracks at that seam on the cab when it was stripped for painting and knock on wood no cracks have appeared in the 5 years its been on the road since it was painted.

My 41 has the cracks too. Interesting to see the tonner underfloor. Similar to my 41 half tonner but different. I can also account for the odd hole in the firewall flange, and the weld nuts (battery tray).

The half ton has four mounts each side, the middle two mounted solid and the end ones mounted with springs, presumably to accommodate frame twist on uneven roads.

I thought the cabs were the same from 40-47 for all trucks. What difference do you see on the floor? In 40 on the 3/4 Ton and larger the gas tank was located in the cab which sat in the large depressed area with the hole in it, which is the only obvious difference that I can think of. As I recall the 1/2 tons used the automotive frame which for 40 and 41 were substantially different than the truck frame which might also account for the cracking seen on the 1/2 tons.

My 41 cab has been butchered in that area - I wish it was only cracked! However I had a 46 1/2 ton cab that I sold recently and it also had the cracks. The 47 cab I have has had the lead removed from the joint - not sure whether to re-lead it or just use body filler. I figure if it cracks again the lead will at least hold together a bit better if moisture gets in? Because of the nature of the sheetmetal join I'm not sure if it's possible to guarantee 100% against it ever cracking in the future?
